Exporting a Docker image allows you to create a portable file that can be shared with others or used for backup purposes. The exported file contains the image’s filesystem and metadata. To export a Docker image, you can use thedocker savecommand, followed by the image name and the desired...
Usage: docker export [OPTIONS] CONTAINER Export a container's filesystem as a tar archive Options: -o, --output string Write to a file, instead of STDOUT 1. 2. 3. 4. 5. 6. 7. 8. 从帮助文档看,docker export 导出的是容器文件系统。 导出容器快照到本地文件 [root@ centos]# docker ex...
docker save is now able to export images from all tags of the repository. Hide push upload progress of manifests, configs and indexes (small json blobs) to match the original push behavior. Fixed docker diff containing extra differences. Fixed docker history not showing intermediate image IDs fo...

1)Dockerfile的指令每执行一次都会在docker上新建一层,所以尽量合并RUN。 2)exec执行格式是JSON数组,必须使用双引号描述。 3)exec格式不调用命令行shell,需要使用shell格式或者路径。如RUN [ "echo", "$HOME" ]不生效,需要使用RUN [ "sh", "-c", "echo $HOME" ]。

其中,/path/to/filesystem是文件系统的路径,new-image:tag是新镜像的名称和标签。更多关于docker import命令的使用说明可以参考Tencent Cloud Docker命令行工具参考文档。 Docker从文件系统拉入/导入的优势包括: 快速部署:通过将文件系统的内容导入到Docker镜像中,可以快速将应用程序及其依赖的环境打包为一个镜像,并在任...
